QA/QC

Quality is Key

RTD is highly automated and uses computer-driven technology to maintain full in-house control over raw materials for the FRC products: degree of polymerization, mechanical properties and dimensional tolerances- to name a few- on all of our posts. The long rods produced by pulltrusion are first visually inspected for aesthetic or physical defects.

According to ISO specifications, samples from each production run are taken and subjected to flexural strength testing.

Interlaminate Shear Strength (between the fibers and matrix) and degree of polymerization (99%) are also confirmed. Upon passing these tests, the rod material is machined into the final post shapes using state – of - the-art computer-driven shaping machines, to within tolerances of two hundredths of a mm.

These dimensional specifications are then confirmed with high-tech scanners looking for concentricity and tolerances.

Our ISO-mandated inventory control system facilitates tracking of all lot numbers of our material after it leaves our docks.

The RTD spirit of quality control also extends to our accessory products, drills composite resins and discs. Our products are registered in many countries, and were the first fiber post to be registered with the US FDA and Canadian Health Dept. Registration is now being completed in such large countries as Russia, Japan, China and Mexico. Of course to achieve this, all the RTD products that stay in the mouth must be proven biocompatible under universal standards.
